  # Key can be a region, availability zone, or local zone.
  # Key CANNOT be an Availability Zone ID or Wavelength Zone.
  # Local zone keys may be incomplete.
  # WARNING: If a current local zone mapping conflicts with a future region mapping,
  #   we may change the local zone mapping in order to keep the region mappings consistent.
  #   This is particularly likely to happen with the "fixed" mappings, so we recommend using
  #   the "short" mappings if you plan to use local zones.
  # For some degree of future proofing, we provide mappings for some AZs that do not yet exist.
  # INCLUSION IN THE MAP does NOT necessarily mean the region or AZ exists.

  # See https://github.com/jsonmaur/aws-regions for complete list of regions

  # to_display_name maps full region names to geographic display names
  # using https://github.com/aws/aws-sdk-java/blob/master/aws-java-sdk-core/src/main/resources/com/amazonaws/partitions/endpoints.json
  # as a reference source, since there is appears to be no API available.
  # Note that https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html
  # claims you can get display names from `aws lightsail`, but Lightsail is not available in
  # all regions, so its list is incomplete.
  #
  # The map contents can be regenerated (will need to be reformatted with `terraform fmt`) with:
  # curl -sSL https://raw.githubusercontent.com/aws/aws-sdk-java/master/aws-java-sdk-core/src/main/resources/com/amazonaws/partitions/endpoints.json \
  #  | jq -r '.partitions[] |select( .partition | test("aws(-cn|-us-gov)?$") ) | .regions | to_entries |.[] | "\"\(.key)\"  = \"\(.value.description)\""'
